According to various embodiments, when a metal material is used as a housing of an electronic device in an antenna device using a PIFA or a monopole antenna radiator, even if a sufficient antenna effective volume is secured, the radiation efficiency of the antenna may decrease and interference may occur. In addition, the same problem occurs when metal devices such as USB connector ports, speaker devices, microphones, ear jack assemblies, and vibrators are adjacent to each other.This is a problem when a high voltage is induced in the open end region of the antenna radiator.
